Quadratic discriminant analysis (QDA) is a widely used statistical tool to classify observations from different multivariate Normal populations. The generalized quadratic (GQDA) classification rule/classifier, which generalizes the QDA and minimum Mahalanobis distance (MMD) classifiers discriminate between populations with underlying elliptically symmetric distributions competes quite favorably...

this paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. a novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. parameters of the fuzzy estimator are adapted to minimize the estimat...

background citation analysis as one of the most widely used methods of bibliometrics can be used for computing the various impact measures for scholars based on data from citation databases. journal citation reports (jcr) from thomson reuters provides annual report in the form of impact factor (if) for each journal. objectives we aimed to evaluate the citation parameters of hepatitis monthly by...

abstract in order to study the effects of quantitative and qualitative traits on cooking characteristics and protein percentage of 15 red bean genotypes, a randomized complete block design was conducted with three replications in normal irrigation and drought stress. these traits were measured in farm and nutrition laboratory employing international standard of ciat. analyses of variance showed...

relationships between soil factors and vegetation types in playa of damghan was investigated. six vegetationtypes including artemisia.sieberi, arundo. sp, artemisia.sieberi-peganum.harmala, alhagi.cammelerom,artemisia.sieberi-petropyron.sp, tamarix.passerinoides-halocnemum strobilaceum. one bare land was recognized inthe study area and the research was conducted within mentioned types. canopy p...

eight genotypes of spring safflower (carthamus tinctorius l.) were evaluated for several physiological traits under stress and non-stress water regimes. data were analyzed using principal factor analysis. the factor analysis technique extracted six factors under non-stress conditions. six factors explained about 80% of the total variation, and only 40% of the variance was accounted for by the f...
